7.1. List Literals, list ranges

Things in () separated by commas are called a list of things.
A list is an ordered set of scalar values.
Examples of lists:

(1, 5.2, "apple")          # 3 values 

(1,2,3,4,5,6,7,8,9,10)     # nice but we are too lazy, so we write this:
(1..10)                    # same as (1,2,3,4,5,6,7,8,9,10)
('a'..'z')                 # all the lowercase letters

("apple", "banana", "peach", "blueberry")   # is the same as
qw(apple banana peach blueberry)            # quote word

($x, $y, $z)               # We can also use scalar variables as elements of a list
